According to Fischer et al., the planet takes around 2,391 days, or 6.55 years, to complete an orbit. This configuration is similar to the configuration of Jupiter and <a href="/wiki/Saturn" title="Saturn">Saturn</a> in the Solar System, with the orbital ratio (close to 5:2) and mass ratio roughly similar.<a href="#cite_note-fischer-23">[22]</a> Subsequent measurements failed to confirm the existence of the second planet, and it was noted that the dataset used to determine its existence left the planet's parameters "almost unconstrained".<a href="#cite_note-24">[23]</a> Analysis of a longer dataset spanning over 6,900 days suggests that while a second planet in the system is likely, periods near 2,500 days have a high false-alarm probability,[<a href="/wiki/Wikipedia:Please_clarify" title="Wikipedia:Please clarify">why?</a>] and the best fit model gives an orbital period of 7,586 days at a distance of 7.73 <a href="/wiki/Astronomical_unit" title="Astronomical unit">AU</a> from the star. Nevertheless, the parameters of the second planet are still highly uncertain.<a href="#cite_note-wittenmyer-25">[24]</a> On the other hand, the Catalog of Nearby Exoplanets gives a period of 2,190 days, which would put the planets close to a 2:1 ratio of orbital periods, though the reference for these parameters is uncertain: the original Fischer et al. paper is cited as a reference in spite of the fact that it gives different parameters,<a href="#cite_note-fischer-23">[22]</a><a href="#cite_note-cne-26">[25]</a> though this solution has been adopted by the <a href="/wiki/Extrasolar_Planets_Encyclopaedia" title="Extrasolar Planets Encyclopaedia">Extrasolar Planets Encyclopaedia</a>.<a href="#cite_note-EPE47Umac-27">[26]</a> In 2010, the discovery of a third planet (<a href="/wiki/47_UMa_d" class="mw-redirect" title="47 UMa d">47 UMa d</a>) was made by using the <a href="/wiki/Bayesian_Kepler_Periodogram" class="mw-redirect" title="Bayesian Kepler Periodogram">Bayesian Kepler Periodogram</a>. Using this model of this planetary system it was determined that it is 100,000 times more likely to have three planets than two planets. This discovery was announced by Debra Fischer and P. C. Gregory. This 1.64 <var>M</var>J planet has an orbital period of 14,002 days, or 38.33 years, and a semi-major axis of 11.6 AU with a moderate eccentricity of 0.16.<a href="#cite_note-bayesian-20">[19]</a> It would be the longest-period planet discovered by the radial velocity method, although longer-period planets had previously been discovered by <a href="/wiki/Direct_imaging" class="mw-redirect" title="Direct imaging">direct imaging</a> and <a href="/wiki/Pulsar_timing" class="mw-redirect" title="Pulsar timing">pulsar timing</a>.
